VirtualBox on a Windows 11 operating system Python command runs as python3 1 I created a new repository based on the caravel user project 2 I followed the steps until lt make setup gt command and verified they ran without errors the environment variables were set properly 3 I ran the setup command and got some warnings regarding Docker 4 There are errors regarding permission denied to access

Hello and welcome Are you targeting sky130 or gf180 How much RAM did you allocate to the virtual machine in VirtualBox

Philipp Gühring · Answer

I think DOCKER SWAP and DOCKER MEMORY are not needed at least I didn t need them yet With ROUTING CORES you could define how many parallel CPU cores should be used for routing you might want to increase it if you still have enough RAM left and the processor utilisation isn t too high

Philipp Gühring · Answer

But the STD CELL LIBRARY is an interesting option which I would suggest to set now there you can define which standard cell library should be used

Philipp Gühring · Answer

Regarding the permission errors I would suggest to try it as root by using su or sudo or you could try to add your username to the docker group in etc group

Dorin Emil Calbaza · Answer

Thanks will ty to add myself to docker group sudo or su root did not work As for RAM standard cells etc I just want to get a feel how the tools work openlane magic layout and simulators first then will try to submit something

Dorin Emil Calbaza · Answer

I added myself as user in the docker group deleted the folder and started from git I get the same warning and errors I could not find the command that calls the docker daemon

Philipp Gühring · Answer

Have you installed docker already

Dorin Emil Calbaza · Answer

Yes I found out that I needed to add myself to the docker group My issues came from a fresh installation of UBUNTU It has python but also needs pip I list below the commands that add docker and pip in ubuntu as well as what is needed to make them work properly After that I was able to run make setup without issues ``` Commands to install docker and python pip module in Ubuntu They are needed docker install and adding user name to docker group sudo apt get remove docker docker engine containerd runc sudo apt get update sudo apt get install docker ce docker ce cli docker buildx plugin docker compose plugin sudo usermod aG docker lt user name gt sudo docker run hello world install pip sudo apt update sudo apt install python3 pip sudo usermod aG docker dorin python3 m pip version good time to reset your ubuntu```
